METALLIC WINDOW.

Application filed December 3, 1925. Serial No. 72,946.

My invention relates to windows, and is more especially concerned with sliding inetallic windows such as are widely. used in modern fireproof buildings. Various ob jects and advantages of the invention are, in general, promoted and enhanced by sheet metal construction. Among the advantages that can be realized through the invention ire simplicity and ruggedness of construction; ease, convenience and low cost in manufacture and installation; tightness against the weather, etc.; and easy, free operation of the sash. In suitable forms of embodiment, such as hereinafter described, the invention aifords the advantage of rugged sash guides, not readily distorted, as well as the capacity foreasy adjustment to take care of minor variations in window-- frames ands-ash.

In the drawings, Fig. I is a front elevation e., a viewfrom the inside) of a window convenientlyembodying my invention. 7

The window shown in Figs. IVII has a frame consisting'of a lintel or head 15, opposed jambs 16, 16 and sill 17, all of hollow sheet metal construction. The jambs 16 are provided with removable tubular guideways 18, 19 for the sashes, shown of squared tubular form. The tubes 18 and 19 for the upper and lower sashes 20 and'21 are separate, but side by side in contact with one another. These tubular guides 18, 19 are detachably secured at the inner jamb face: when detached, they can be moved sidewise across the jamb face with the sashes, for purposes of installation-or removal. In the present instance, the jambs 16 are open at their inner faces practically from top to bottom, and the tubular guides 18, 19 are secured over and close the jamb openings. As shown in F igs. II and III,

the tubular guides 18, 19 are securedand held in place partly by screws 22 through them and partly by stops 23,v 24 at their remote (outer and inner) edges;

In the present instance, the outer sto 23 (See Fig. III) consists ofa shoulder a ong the outer corner of the jamb face, formed by appropriately bendingthe sheet-metal 0f the jamb wa1l, while'the inner stop '24 is removable, consisting of an angle bar secured to the jamb face by Y screws 25. Besides being held in lateral position between the stops 23, 24, the guides 18,. 19 may be held in place transversely, against the jamb face, by retaining means carried by the stops, I

As shown, these retainingmeans consist. of shoulders or flanges 26, 27011. the stops 23,

24: that overhang in front of the j amb face,

so as to project over the edges of the guides 18, 19. Thus each of the stops 23, 24 and its flange or shoulder 26,. 27 in effect forms a socket facing across, the jamb face, to take the corresponding guide tube edge; The flange 26 of the outer stop 23 consists of a heavy strip of sheetmetal secured by screws 28 to the inner face of this stop, (and also forming; an ornamental molding outside of the j amb 16) while the flange 27 of the inner stop 24 is. formed byits own bent over edge.

' ends.

As shown, the inner step 2 1 is similarly flanged around the inner corner of the jamb box, at 29. In cross-section, this inner stop is a more obtuse angle than the angle between thejmnb' face and the tube edge, so as to'cl'amp the tube 19 firmly when the screws are tightened up.

As shown in Figs. 11171, securing screws 22 for each inner guide tube 19 extend through the latter at its upper and lower 7 The screw 22 at the upper end of eaeh'tube 19 takes into astout sheet metal bar 31 secured to the-edgesot the jamb wall across the opening in its inner face, and j'oggled inward flush with the outer surfaces of this wall, against which the tubes 18 and 19 seat. "The screw 22 at the lower end of the tube 19 takes into the wall of a stout sheet metal pan 32 (hereinafter fu'rth'er described) in the lower end of the ja'mb 16, a liner 33 being interposed to seat the tube ends properly. At their adjacent edgesythe guide tubes 18 and 19 are additiOnallysecured' by the screws 31 which extend through the meeting rail wedge block 35 (Fig. H)"and thetube 19 and take into a joggled bar 36 like the'bar 3*1.

As-shown in Figs. H V, the sashes 20, 2-1 are composed of overlapping front and rear (outdoor and indoor) strips of sheet metal STand 38, the former constituting the principal structuralelements of the sashes, while the latter serve as removable glazing strips "The front strips 37 which form the side rails of the sash are engaged in the vertical guide slots of the tubes 18, 1.9 and thesash cables (chains) 39 are attached to the side rails 37 in the tubes. In the present instance, there isispace for edgewiseplay of th'esash outside the side rails 37, between th'e' latter'and the rear walls or backsor" the tubes 18, '19, and the edgewise position of the sash is controlled by'engagement with the inner sides'or walls of the tubes 18, 19. As shown in Figs. IIIV, the side'rails 37 of the sash-have lateral flanges 10 extending their whole height, with isolated guide projections 11 near their uppcrand lower ends forengaging the inner tube walls from the rear atinside, and hooks 12 for the attach.- ment of the sash cables 39.. These guide projections 411 may consist'of pimple-like enibossments 'of'the sheet metal of the side rails 37; or they may consist 01" roundheaded screws (of bronze, "for example) tappec"thioi1glr the side rail llan'gesdll and provided with lock nuts 11*, as shown in Fig. VII.

1 In installing or replacing the sashes 2t), 21,'the guide tubes 18, 19 are slipped on their side rails37 endwise. 'l he inner steps 24: beingremoved (or not yet attached), the outer guides 18 are introduced sidewise between "the j ambs 16- and seated against them and in the above described sockets of the put in place, and the inner stops 2d put on.

The screws 22 and 84; and the meeting rail wedge-block 35 are then put 1nplace,and all the screws finally tightened up. To remove the sashes 20, 21, these operations are simply reversed.

In Fig. VIII is shown a modification 0t the sashes in which the side rail flanges 10 are dispensed with, and the guide projections 11 and sash cable attachment hooks 42 formed or mounted on angle lugs 48 welded to the side rails 3'7 near their upper and lower ends. In Figs. IX and X, the sash cable hooks 42" are formed in the edges of the fiangeless side rails 37" and the edgewise position of the-sash is controlled by external engagement with the inner tube walls. As shown in Fig. IX, the sash members 38" are slotted near their edges, at 1 1, and the portions 15 outside the slots 14 are bent outward to form guide projections for engaging the tube walls externally.

As shown in Figs. IV and V, the pulleys as over which the sash cables 39 extend from the counterweights 17 to the hooks 42 on the sashes are mounted in the jamb face just below the head 15, their housings 48 being secured by screws 49 to the bar 31 already mentioned and to the wall of a pan 50 itself secured in theupper end of the jamb 16, like the pan 82'at its lower end, and having its side joggl'ed to seat the pulley housings, like the bar or plate '31. As the pulleys as project beyond the inner jamb face, the corresponding sides of the tubes 18, 19 are cut away (to the extent ofabout half their thickness) at their upper ends, to clear the pulleys and permit the tubes to be moved across the jamb face as above de scribed. As shown in Fig. V, one of the pulley housings 418 may be provided with a flange 48 to fill the opening that would otherwise exist in the adjacent tube sides and prevent leakage of air from one tube to the other.

As shown in Figs. 11 and IV. the lower and upper ends of'the jambs l'6abut against the sill 17 and the head 15 and are secured by bolts 51, 52 taking through the pans 32 and 50. The sill 17is shown of stepped conformation. The jamb is provided with a seat 51 (Figs. Hand VII) for the lower ends of the guides 18. 19, which seatislocated' in the lower end of the pocket in the outer stop, 23, and secured to the sill 17. This seat 54: is shown as of sheet metal panlike construction, \iith'its inner side Wall 55 extending beyond its end to form a continua tion'ott the outer guide edge of the inner tube 19. A small piece 56 (Fig. 11) is secured to the overhanging sill step to form a till) '8 continuation of the inner guide edge of the same tube 19. Thus the side rail 37 of the sash 21 can extend down in the slot clear to the sloping sillsur'face, so that there shall be no influx of air atthis. point. As shown in Fig. II, the top of the seat fi l slopes uplevel, at 59 to enter the channel. The lowupward around the downward-extending.

flange 59 of said rail,"so that the cross sec tion of its tree portion resembles the letter 8. When the sashes 20, 21 are closed, the lower bend of the S engages against the bottom of the channel 58 of the upper sash meeting-rail.

' The thinner inner member 38 of the bottom rail of the lower sash is bent outward to engage the lower step of the sill 17, and is doubled downward and then bent inward and downward to form at downwardsfacing channel over the upper step of the sill. This channel 62 is provided with resilient sheet metal weathering in the form of a thin strip of bronze '63 clamped between the doubled plies of the inner sash member 38 and bent inward and then outward in a sort of bow 6%, to engage the top step of the sill when the sash is lowered.

From the foregoing description, other practical advantages afforded by my invention will readily be apparent, besides those already mentioned. The tubular guides 18,-

19 can be made of rolled sections, and their cross-section assures ample strength and rigidity without excessive thickness and weight of metal. Hence they can be made of non-corrosive metal such as bronze without excessive cost. They are little liable to accidental deformation from the straightness that is so desirable to assure easy operation of the sashes 20, 21. They are easily and quickly put in place or removed.

The sashes 20, 21, likewise, can be built of rolled sections; and when laterally flanged within the guides, as in Figs. III and V, they possess the most ample rigidity without undue thickness or weight lVhen turned outward toward the weather, as shown, the lateral sash flanges 40 tend to prevent high wind and rain, etc., from driving into the guideways 18, 19. The elastic weathering 60, 63 on. the meeting rails and to slide in.

on the bottom rail assures weather-tightness, and can be madeof non-corrodible metal without-undue cost.

The guide projections 41 or l5 are easily adjusted to take care of the usual minor variations of windows in manufactureand installation, by punching or screwing them outv a littlemore if the sash has too much lateral play,, and by filing oil their tops or. screwing them in somewhat if the sash binds or has insufiicient play.

Fig. XI shows the sashes 20, 2l of Figs.

In therecess is a vertical channel Ti'lwvith guide flanges 74, Tel on is sides 75, 75, This channel 73 is secured to tlc bolts .76, and. theedges of its tlan'ges 74, 74 are, spaced lfroin the corners of the recess to ailor d slots for the side rail memberslBT The spaces between the walls of therecessTO and those of; the channel T3 serve as pockets to accominodatethe sash cables 39, which are secured to hooks a2 on the side rail flanges 40 as in Figs. IILV. Preferably, the edges of the side rail flan es il) are separated froin the channel sides I 5,

ji'5 by considerable clearances (e. g.,

inch), as shown, rather than substantially in contact with them. The isolated guide projections ll in the side ra1l' flanges 40 engage the rear or inner vfaces of the guide flanges 7d.

In Fig. Xl, various parts and features are marked with the same reference characters as in FigsfI-VII, as a means of dis pensing with further or'merely r petitive description.
